DEVICE FOR PREVENTING THE ERAUDULENT FILLING F BOTTLES.

SPECIFICATION forming part of Letters Patent No. 500,057, dated June 20,1893.

Application filed January 28,1893. $erial No. 459,989. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN JAMES DUFOUR,

, a citizen of the United States, residing at Paducah, in the county ofMcCracken and State of Kentucky, have invented certain new and usefulImprovements in Devices for Preventing the Fraudulent Filling ofBottles, Jars, or Jugs; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention has relation to an improvement in devices for preventingthe fraudulent filling of bottles, jugs, or the like, and the noveltywillbe fully understood from the following description and claims takenin connection with the annexed drawings in which- Figure 1,is asectional view of abottle neck with the body broken away and showing myimprovements in position therein; and Fig. 2, isa perspective view ofthe improved device removed from the bottle neck, and the valves orballs removed from the frame or holder. As a convenient construction andwith a view to economy I make the frame A, of aluminum wire, tinnedcopper wire, or other light material which will not be afiected by suchliquids as may be placed in the bottle. These Wires a, form a cage orholder as shown, and are turned at their upper ends across each other atb, Where they prevent the upper ball or valvefrom entirely coming out,and the lower ball or valve is prevented from touching the upper one orthe seat thereof by means of a cross wire 0.

B, indicates a band of metal or other suit- I able material, which ismade fast to the branches of the cage or holder, and is provided with adepending conical seat d.

0, indicates a conical seat for the lower ball or valve. This lower seatis also firmly secured to the wire cage or holder at the lower endthereof, and it may have a depending band e, as a convenient means ofsecuring the device into a bottle neck.

The upper ball or valve D, may be formed of glass, or other suitablematerial, while the lower ball or valve E, should be of a lighter orbuoyant substance so that-any attempt to fill the bottle or jug,containing my improvements by inclining the bottle or placing it on itsside, would cause the buoyant valve to float into its seat andabsolutely prevent the induction of any liquid.

I have illustrated the cage as composed of two wires a, bent vmidway oftheir length so as to cross each other at the point I), and secured attheir lower ends to the band of the conical seat 0, and further securedto the band B, but it is obvious that more or less wires may be used andit is further obvious that the cage or frame may be diiferentlyconstructed without departing from the spirit of my invention.

In practice the bottle should be first filled with the brand of liquorit is designed to contain. sufficiently low to permit of the insertionof a cork F, above it, when the said device should be secured bya cementor other adhesive substance which will not injure or affect the liquid.It will be seen that by removing the cork the whole of the liquid or anydesired quantity thereof may be drawn off but any attempt to refill thebottle when placed in an upright position would cause both valves toseat in their conical bearings and close the outlet, while if an attemptshould be made to place the bottle on its side in such a position asto'bring the valves out of their seats and then fill by immersing thebottle in liquid, the inner or buoyant valve will readily check suchfraudulent attempt by floating into its seat, while the outer ball orvalve if used alone might permit, the introduction of a certain quantityof liquid. The cross wire 0, will prevent-the inner valve from passingtoo far from its conical seat.

Having described my invention, what I claim is 1. A device forpreventing the filling of bot- I The device is then placed in the neck'filling of bottles, comprising the cage like one in each seat,substantially as and for the frame, formed from the wires a,crossingeach purpose specified. 10 other, as shown, the band having aconical In testimony whereof I afiix my signature in seat secured to thelower ends of said wires, presence of two witnesses.
